Antepartum hemorrhage with afibrinogenemia, third trimester

This code signifies bleeding from the uterus occurring during the third trimester of pregnancy, specifically when it is complicated by afibrinogenemia. Afibrinogenemia is a rare, severe coagulation disorder characterized by the complete absence of fibrinogen, a protein essential for blood clotting. This combination presents a high risk of severe hemorrhage for both mother and fetus.

Apply this code when documentation clearly indicates antepartum hemorrhage occurring in the third trimester (28 weeks gestation or greater) and explicitly states a diagnosis of afibrinogenemia. This diagnosis typically requires laboratory confirmation of absent fibrinogen levels. Use this code when the afibrinogenemia is identified as a contributing factor or complication of the hemorrhage.

• Ensure documentation specifies "third trimester" and not just "antepartum hemorrhage."
• Verify the presence of afibrinogenemia, not just general coagulopathy or other bleeding disorders.
• Sequence this code as a primary diagnosis when it is the main reason for the encounter, or as a secondary diagnosis if another condition is primary and the hemorrhage with afibrinogenemia is a significant co-morbidity.
